Pool Chlorinator
Troubleshooting
Resources for fixing your chlorinator problems.
Tip: Regular maintenance of your pool chlorinator, whether it’s a tablet feeder, liquid chemical feeder, or salt system, is crucial for effective sanitation. Frequently check chemical levels and adjust the output settings as needed. Clean the feeder to prevent clogs and buildup, and inspect the system for leaks, replacing any worn components promptly. A well-maintained chlorinator ensures consistent chemical delivery for a safe and enjoyable swimming environment while minimizing the need for additional treatments.
Common Chlorinator Problems
Click on a symptom that you are experiencing…
Low Chlorine Levels
Problem:
Low chlorine levels in your pool can lead to algae growth and poor water quality, making it essential to address this issue promptly. This problem may arise from several factors, including insufficient chlorinator output, a malfunctioning tablet feeder, or high water demand.
Action Items:
- Check the chlorinator settings: Ensure that your chlorinator is set to the appropriate output level for your pool size and current conditions. Adjust the settings as needed to increase chlorine production.
- Inspect chlorine tablets: If you are using a tablet feeder, check that the feeder is filled with the correct type of chlorine tablets. Ensure the tablets are not too old or deteriorated, as this can affect their effectiveness.
- Clean the chlorinator cell: If you have a saltwater chlorinator, inspect and clean the chlorinator cell to remove any scale buildup that may be inhibiting its performance. Regular cleaning can help maintain optimal chlorine production.
- Test water chemistry: Regularly test your pool water using a reliable test kit to monitor chlorine levels and other chemical balances. Adjust the chemical levels as necessary to keep your pool water in the proper range.
- Increase circulation: Ensure your pool’s circulation system is working properly. Low water circulation can lead to uneven chlorine distribution. Run the pump longer or check for any clogs in the plumbing.
- Shock the pool: If chlorine levels are significantly low, consider performing a shock treatment to quickly raise chlorine levels. Follow the manufacturer’s instructions for the appropriate shock treatment based on your pool size and current conditions.
- Monitor environmental factors: Be aware that factors such as heavy rain, high bather load, or organic debris can lead to decreased chlorine levels. After such events, check and adjust chlorine levels as needed.
Clogged Chemical Feed Lines
Problem:
Clogged chemical feed lines can prevent proper dosing of chlorine or other pool chemicals, leading to imbalanced water chemistry and potential water quality issues. This blockage can result from debris buildup, mineral deposits, or the wrong type of chemicals being used.
Action Items:
- Inspect the feed lines: Visually check the chemical feed lines for any visible clogs or obstructions. Look for any debris, algae, or other buildup that could be restricting flow.
- Flush the lines: Disconnect the feed lines and use a hose to flush out any accumulated debris or chemical residues. Make sure to direct the water away from the pool and other sensitive equipment.
- Check chemical compatibility: Ensure that the chemicals being used in the feeder are compatible with your system. Incompatible chemicals can lead to clogs or damage to the feed lines.
- Use a cleaning solution: If flushing the lines doesn’t resolve the issue, consider using a specialized cleaning solution designed for chemical feed lines. Follow the manufacturer’s instructions for use.
- Inspect and clean the injector: The injector, which draws the chemical into the pool water, may also be clogged. Remove and clean the injector according to the manufacturer’s guidelines.
- Regular maintenance: Implement a routine maintenance schedule to regularly check and clean the chemical feed lines to prevent future clogs. This can include periodic flushing and inspecting all connections for signs of wear or damage.
Exploding / Cracked Housing
Problem:
An exploding or cracked housing in a pool chlorinator or chemical feeder is a serious issue that can lead to hazardous chemical spills and equipment failure. This problem often arises from excessive pressure buildup, overheating, or the use of incompatible chemicals.
Action Items:
- Turn Off Equipment Immediately: If you notice cracks or hear unusual sounds, turn off the chlorinator or feeder immediately to prevent further damage or safety hazards.
- Inspect for Damage: Carefully examine the housing for any visible cracks or signs of stress. If there is significant damage, the housing will likely need to be replaced.
- Check for Pressure Issues: Evaluate the system for signs of excessive pressure. High pressure can occur due to clogs or improper settings. Ensure all components are functioning correctly and adjust settings as necessary.
- Review Chemical Compatibility: Confirm that you are using the appropriate chemicals for your system. Incompatible chemicals can cause reactions that lead to housing failure.
- Regular Maintenance: Conduct regular inspections and maintenance to check for wear and tear on the housing and other components. Replace any worn parts promptly to avoid potential issues.
- Consult Manufacturer Guidelines: Refer to the manufacturer’s guidelines for installation and operation to ensure compliance with safety standards and to prevent issues with the housing.
Tablets Not Dissolving
Problem:
When tablets in your chlorinator or feeder are not dissolving properly, it can hinder the effectiveness of chlorine delivery, leading to imbalanced water chemistry. This issue may arise due to low water flow, incorrect placement of the tablets, or the use of outdated or improperly stored chemicals.
Action Items:
- Check Water Flow: Ensure that the water flow through the chlorinator or feeder is adequate. Low flow can result from clogged lines or pump issues. Clear any blockages and check pump performance.
- Inspect Tablet Placement: Make sure that the tablets are placed correctly in the feeder or chlorinator. Tablets should be positioned according to the manufacturer’s instructions for optimal dissolution.
- Use Fresh Tablets: Verify that the tablets are not expired or damaged. Old tablets may not dissolve effectively. Always store chemicals in a cool, dry place to maintain their potency.
- Adjust Feeder Settings: If your chlorinator has adjustable settings, ensure they are set correctly for the type and size of tablets you are using. This can impact the rate of dissolution.
- Increase Circulation: Improve pool circulation to help distribute chemicals evenly. This can be achieved by running the pump longer or using a pool brush to promote water movement.
- Consult Manufacturer Guidelines: Always refer to the manufacturer’s guidelines for specific recommendations regarding the use of tablets and operation of your chlorinator or feeder.
- Consider Upgrading Equipment: If the problem persists, you might want to evaluate the effectiveness of your current chlorinator. Upgrading to a more efficient model could improve chemical delivery and overall pool maintenance.
Can’t Remove Lid
Problem:
If you’re having trouble removing the lid from your pool chlorinator or tablet feeder, it can be frustrating and prevent you from adding or changing chemicals. This issue is often caused by chemical buildup, pressure accumulation, or improper sealing of the lid.
Action Items:
- Inspect for Chemical Buildup: Check the area around the lid for any chemical residue or buildup that may be causing it to stick. Cleaning the lid and surrounding area may help.
- Release Pressure: If the chlorinator or feeder is pressurized, it may be necessary to relieve the pressure before attempting to remove the lid. Refer to the manufacturer’s instructions for safely releasing pressure.
- Use Lubrication: Apply a small amount of food-safe lubricant around the sealing area of the lid to help ease removal. Ensure that the lubricant is compatible with pool chemicals.
- Wiggle or Twist Gently: Gently wiggle or twist the lid while applying upward pressure. Be cautious not to force it, as this could damage the unit.
- Check for Proper Alignment: Ensure that the lid is aligned correctly with the body of the feeder or chlorinator. Misalignment can prevent the lid from being removed easily.
- Use Tools Wisely: If the lid remains stuck, consider using a rubber strap wrench or similar tool to provide extra grip. Avoid using excessive force that could break the lid or housing.
